Description of selected variables:
&lt;recnum&gt;       Unique record ID number - Unicon created

        Each observation is assigned a unique id number, facilitating later
        merges with the SAME file should the user wish to extract additional
        variables at a later time.  This ID variable can not be used to match
        different files across years; instead, refer to the discussion in
        Appendix S.  The maximum value of this variable is the total record
        count from each file.  There is no corresponding variable to be found
        in the census files; therefore, no column numbers are listed here.

        1962            Universe - all person records

               Rotation groups 4 and 8 are not in the March Income sample in
                 1962.  Variables in columns P133-P172 do not contain valid
                 data for these two groups. (per Census docs)
                 Comparing these values to the Feb-Mar match variable (match)
                 it appears that the month-in-sample value for 1962 is actually
                 the MIS value for February, not March.  MIS groups 4 and 8
                 show up as non Feb-Mar matches.  If the March MIS value were
                 listed here, it would show MIS groups 1 and 5 as non Feb-Mar
                 matches.
               Rotation groups 4 and 8 are not in the 1964-1965 files.

               In the 2001S and 2002 files, the original mis values were not 
               the values used in the creation of sample weights.  The Census 
               provided patch files with the corrected mis values for these
               two years. 
              
               As part of the January 2003 changes in the weighting scheme of 
               the CPS, the Census Bureau changed the way it weights rotation 
               groups.  Instead of preserving the eight groups at the state 
               level, the Bureau now pairs rotation groups as follows:
                  1 & 5     2 & 6     3 & 7     4 & 8
               As a result, if one compares distribution across the eight 
               rotation groups (using H-MIS) by state in the 2002 and preceding
               March ASEC files with the same distribution in 2003 and 2004, 
               significantly more apparent variation is seen in the distribution
               in 2003 and 2004.  This apparent variation disappears when the 
               eight rotation groups are collapsed into the four paired groups. 
               New state-by-state calculations are shown in the Appendix AA.
               The new pairing of the groups was part of the overall redesign 
               of CPS weighting.  The pairing allowed the Census Bureau to 
               improve weighting routines by increasing cell sizes, thus 
               yielding better results when controlling for detailed demographic
               distributions at the state level.

               Note to those interested in matching: This variable is
               transcribed by the interviewer from rotation to rotation.  So
               this should be a unique identifier for an individual within the
               household.  In the initial rotation (mis = 1), the value should
               be equal to perid.  In 1976, the questionnaire went through a
               major revision and it was not until 1979, when the CPS began to
               include lineno again.

               In 2002+, the Census dropped the topcoding of age to 80, and
               perturbed (scrambled) the value of age for certain records with
               ages 66-80 and less than 12.  They did not allow the revised
               ages to go outside those barriers; that is, no one whose age
               was 67 ended up with an age of less than 66, no one aged 9
               ended up with an age greater than 11.

        Note:  Universe - all interview records (1&lt;=popstat&lt;=3)
               In Jan 1996, the Census revised procedures for editing and
               allocating the race variable.  All "Other" responses were
               allocated into one of the 4 main race categories.  This was
               done to offset a major increase in "Other" responses which
               caused severe underestimates of the American Indian and Asian
               Pacific Islander populations.  Due to this, one should use
               caution when making comparisons between 1995 and 1996 data,
               especially for those identifying all four race groups.

               CAUTION - The 'select' and 'unselect' options should be
               used carefully with the UNICON RECODE, as selection occurs
               after recoding of the variable.  (i.e., The options use the
               recoded values rather than the original raw values.)

               2005 Matching (source May 2004 BLS data layout) -
               To match backward in time from 2005 , use hhid.    
               To match 2005 forward, concatenate hhid with hhid2 to uniquely 
               identify households.  
               hhid  is the same characters in columns  1-15 of peridnum
               hhid2 is the same characters in columns 16-20 of peridnum

               Beginning in 1994 through the current year, there is a problem
                 with duplicate HHIDs for different household units. 
                 The problem is particularly severe starting with the SCHIP-
                 expanded sample in 2001 (the 2001S data).  See Appendix S for
                 further discussion.  When identifying a household within a 
                 file, the variable hhseq should be used.  This variable 
                 appears to have no problem with duplicate values.
                 However, when matching records across files, it is necessary to
                 use HHID.  Adding geographic variables to the sort (state, 
                 cntyfp) may aid in uniquely identifying household units.
                 When that is not enough, we suggest that household units be
                 identified by using both hhid and hhseq, then use 
                 demographic variables (sex, age, race) to match up 
                 individuals within the household, thus insuring that the 
                 proper hhid / hhseq units are matched across years.

               In 1994 and 1995 there appear to be duplicate famnum's within
                 household id.  The Census response (10/98) to this matter
                 follows: 'There is a problem with the household id's in 1994
                 and 1995 in that there is not enough detail present in the 12
                 digit number.  This number must be concatenated with the census
                 state code to make these numbers more unique.'  Use _hhid.

               In 1994, this variable on the tape release was incorrect.  The
                 corrected values were released on-line. Unicon has merged the
                 new values onto this file.  The corrected hhid is found here.
                 The original value is found in the variable hhid94.

               In 1976, there are 103 people grouped into one household.  By
                 using the hhseq value in the Unicon recode _hhid, the user
                 creates more unique households but loses the ability to match
                 the households to the 1975 file.

               To match 1975 to 1976, trim off the last character of 1975 
                 (the 5th digit of segnum). It is a check digit that should
                 not be used to match these two years.

               In 1973-1975 we have used random and segnum, read in as one
                 variable.  IT IS NECESSARY TO USE THESE VARIABLES ALONG WITH
                 THE SERIAL NUMBER (sernum) which is found at the end of the
                 record.  As the three variables are not adjacent, this
                 software has not read them in as one variable, hhid.  Use
                 _hhid for a Unicon recode which does combine these variables.

               In 1968-1972 we have used random and sernum, read in as one
                 variable.  In 1976 we have used random, segnum and sernum,
                 all read in as one variable.  For 1968-1972 and 1976, these
                 are the variables suggested by the Census documentation to use
                 when trying to match households across years.  These should
                 adequately identify a household but it is still not 100% 
                 foolproof. (Our investigation shows that this does not work
                 for 1972; it is necessary to use an alternate method for this 
                 year: Unicon has created a new hhid, incremented every time
                 hhrel =1 or 32 (head).)

               In 1962 we have used serial number as an identifier as suggested
                 by the Census documentation. It is the same as sernum.  Tabs
                 with relhd and hhrel indicate that this is not foolproof.

               In 1996-2002 the top, nonrecoded value is $150,000. 
               In 2003 forward the top, norecoded value is $200,000.
               ABOVE this, the individuals are grouped by sex, race/origin, 
               and worker status.  A mean income value is calculated within 
               these groups and assigned to the individuals.  The largest mean 
               value is shown as the 'Top value'.

               See Appendix H.3 for details on average replacement values for
               earning fields in 1996 forward.

               In some years, the topcode flags are inconsistent with the actual
               data.  See Appendix H.4 for details.

               The various income fields have been topcoded to prevent
               disclosure.  In 1989, blanks were represented with unreadable
               characters.  The data in this field were mostly unreadable
               characters, which were converted to missing.  Only 611 out of
               144687 person records had data which could be translated.  All
               611 records had a value of 1.  The missings should be set to 0.

               In some years, the top code flags seem to be inconsistent with
               the actual data.  See Appendix H.4 for details.

                        In 1962, the documented code values are suspect.  By
                        running two-way frequencies with other family structure
                        variables, Unicon has mapped out a different set of

                        this data to help.  The documented codes are shown in
                        parenthesis.

        Note:  Universe - all interview records (1&lt;=popstat&lt;=3)
               In Jan 1996, the Census revised procedures for editing and
               allocating the race variable.  All "Other" responses were
               allocated into one of the 4 main race categories.  This was
               done to offset a major increase in "Other" responses which
               caused severe underestimates of the American Indian and Asian
               Pacific Islander populations.  Due to this, one should use
               caution when making comparisons between 1995 and 1996 data,
               especially for those identifying all four race groups.

               CAUTION - The 'select' and 'unselect' options should be
               used carefully with the UNICON RECODE, as selection occurs
               after recoding of the variable.  (i.e., The options use the
               recoded values rather than the original raw values.)

               With the introduction of new geographic codes in May 2004,
               the term central city has been replaced by principal city.

               Whenever possible this code identifies specific central cities
               in a CBSA or MSA/PMSA that have multiple central cities.  
               In order to uniquely identify a specific city, this code must

               wgtalt - alternate March supplemental person level weight (*100)

        Code:  The Census Bureau omits decimal points from the data.

               THE USER MUST DIVIDE VALUES BY 100 TO OBTAIN CORRECT WEIGHT.

               In 1963-1967, handwritten notes in the margin indicate that
               there are two implied decimals.  Also, this variable may be
               negative.

               Some years have alternate weights (see wgtalt):
                  1980  wgt is based on 1970   wgtalt is based on 1980
                  1990  wgt is based on 1980   wgtalt is based on 1990
                  1993  wgt is based on 1980   wgtalt is based on 1990
                  2000  wgt is based on 1990   wgtalt is based on 2000
                  2001  wgt is based on 1990   wgtalt is based on 2000
                  2001S wgt is based on 2000   wgtalt is based on 1990

               The 2002+ weights are 2000-based (per Census email 9/02).
               (Note: the 2002+ files are actually SCHIP files and are most
                      comparable to the 2001S file).

               In July 2005, the Census re-released the 2004 weights.  They 
               were recalculated based on more age detail for children to
               provide better estimates of children by single year of age.
               These TST weights will be the official weights in 2005.

        Note:  Universe - all person records
               Apply this weight to ALL variables in 2001 forward and to
               supplemental variables in earlier years.  Final weight (wgtfnl)
               may be applied to basic variables before 2001.

               The following may be used as weight origination guidelines:

               The household record gets the householder weight.
               The Primary Family family record gets the householder weight.
               The Nonfamily Householder family record gets the householder wgt.
               The Related subfamily record gets the subfamily head weight.
               The Unrelated subfamily record gets the subfamily head weight.
               The Secondary Individual record gets the secondary indivdual wgt.

               See discussion of weights in Appendix Q.
